Heatsink Clearances and Overclocking

FIC did a fair job at clearing out the
CPU socket area of obstructions, it's a shame the mounting holes are
gone though.

Heatsink Clearance Measurements

Top Clearance:

15 mm

Bottom (cam) Clearance:

7 mm

Left Side (arm) Clearance:

18 mm

Right Side Clearance

16 mm

Socket Mounting Holes:

N/A

Max. Heatsink Base Dimensions:

~86x76 mm

Note: Approx.
measurements are made from the edge of the socket (not the clips) to
the closest obstacle taller than the ZIF socket
itself.

The socket is 51mm across, and 62mm from
top to bottom.

Installation of heatsinks about the size of the Vantec AeroFlow
is possible, but if you intend to use something larger like the Thermalright SLK-800
you may have problems (bending capacitors is probably required).

Overclocking:

Because our nifty modded Socket A CPU cooler did
not fit on the AU13's mounting holes (it was made specifically for another board) we did not have high hopes in terms of
overclocking. The first thing I did was remove the Northbridge heatsink and
replace the thermal pad with some regular white silicon paste, which should help things just a bit.

We started to raise the FSB slowly, only 2-3 MHz at
a time but unfortunately our overclocking adventure maxed out at a rather
unimpressive 173 MHz FSB. No matter what we did, we could not get the system
stable past that mark. I'm pretty sure that it was the Northbridge that was
holding me back here, perhaps if it had better cooling we could have gotten the
AU13 higher.
